It's not about Caron Butlers locker room presence. It's about the general concept, that you need veterans in order to have a stable and hard working locker room. I don't believe in this concept. I believe groups of individuals work best, when there is a bonding between the members, which is easiest to achieve, when they are of a roughly similar age. So in general the talk about the so called veteran locker room guys is nice for the media, but may be not that beneficial as most fans and journalist think it is (I feel it's the same like those overrated phrases about "being the first guy in the gym and the last one to leave". If every player that uses this phrase would actually live it, there would be a line in front of the gym in the morning fighting for the pole position to get in

). And like I said - we are not a young team anymore.
Hitting a few jumpshots is not the same like giving quality minutes. Caron Butler is an aging offensive minded player. We on the other hand desperately need defense and to play good defense you need good defenders, because team defense won't get the job done all the way.
I never was on the "blame Karl for everything"-train. Karl couldn't find minutes for Butler and most likely there was a reason for it, because Karl even played James Anderson over Butler. I can't say that this suprised me, because Butler wasn't good for Detroit in 2014/15 either.
